1//! The `yog` CLI's internals: `yog.toml` parsing, the generated
2//! `.yog-build/` workspace, `.yres` resources, `content/` blocks and items,
3//! `.yui` screens and `#[yog_export]` crates.
4//!
5//! Not for external use — a library only so the `yog` binary, its tests and
6//! its benches share the code. No API stability, not published separately.
